We are given coordinates of A, B, C and D :
A(2, 4), B(9, 8), C(-1, 2), and D(3, -5).
Now, we need to find the slopes of AB and CD.
Slope of AB is :
.
Slope of CD is:
.
<em>Slope of CD is negative reciprocal of slope of slope of AB. </em>
<h3>Therefore, lines AB are CD are perpendicular.</h3>
The picture has a quadrilateral with ABCD angles.
∠A=90° is right angle
∠B=105° is obtuse angle
∠C=75° is acute angle
∠D=90° is right angle
Given that,
The picture has a quadrilateral with ABCD angles.
The angle are
∠A=90°
∠B=105°
∠C=75°
∠D=90°
We have to clarify the angles of the quadrilateral.
∠A is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.
∠B is obtuse angle because a form of angle known as an obtuse angle is one that is always greater than 90° but less than 180°.
∠C is acute angle because an acute angle is one that is smaller than 90 degrees in length. L-shape shapes at 90°
∠D is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.
